I did that (made the new level; added Nav Mesh Volume, Added ‘Floor’ Collision Pre-Set, Hit Build.) The character get’s booted off the level, and the icon for Player Start states “Bad Size”. I looked it up online, and apparently the game engine won’t allow a character to be inside a collision box (when looking up for the reason behind the ‘Bad Size’ Error.). I get rid of Collision ‘Floor’, no problems, but I can’t move. I have Collision ‘Floor’, my player can move but is off the level and falls downwards.
